SOURCE: battery removal on a 2004 GMC Envoy

The battery is on the right side behind the fuse box. You need a metric set to undo the 3 screws. Theres one that attaches to the body, one to the bar that goes along the top, and theres one on the left side below the vacuum hose and air induction. After you've taken out those three, you should lift the whole thing out(battery and shroud) together. It's hard to take the shroud off before you lift the battery out. After that, you have to pry the shoud off the battery. The two terminals in the back make it hard. Then just go to any auto parts store and they'll give you a new one.

SOURCE: Gmc Envoy 2004 Seat heaters

I have the same problem with my 2004 HD Sierra. I found that the "MBEC" 50 amp fuse in the under hood fuse box had blown. Replaced that and it works now. This has happened twice in 2 years.

SOURCE: charge ac

It is located under the hood in the larger of the 2 AC lines, this large line is the low pressure line, also check on the round can the low side line connects to as it can be on that as well, that part is called the Accumulator/reciever drier

SOURCE: 2002 gmc envoy shuts off when i turn on the ac whil ideling

If it does it when idling I would suspect an IAC motor (Idle Air Control). If it is opening too slowly the added air the motor needs will not be supplied fast enough and the engine will kill.

It could be other things also but this is where I would start.

Probably an AC compressor problem - if it is even partially seized, when the AC clutch engages that will stall the truck.

sound to me like a manifold vacume problem. your enviroment control is ran by vac and vac leak or low vac will create a stall condition. ck vac. at switch at heater core box. you will notice a vac line that moves the flap to cover core,for ac, or open for heat
,if no vac, ck firewall in engine compartment. you will see a vac line that travels thru the fire wall .trace back to source checking for cracks and breaks.

Where is the egr valve located on a 2004 gmc envoy xuv, and will a bad egr valve cause rough idle and rougher idle when ac is turned on?


Yes it could cause that. the EGR is near the rear of the engine, if it is leaking it will sizzle water when you touch it with wet fingers.

Stalling and it stops stalling when you turn the heater off


Sounds like you're running the whole vehicle off the battery. Have your alternator tested

I have a 2004 gmc envoy and when you connect the battery back and turn on the ac or heater the car turns off.do you have to reset something...it will go away but after a while..


Assuming you mean that the engine shuts off or stalls, and also assuming you have the 6 cylinder engine. The mostly likely cause is a dirty throttle body. If you are a handy person you can do it yourself. Go to www.trailvoy.com and do a search on throttle body cleaning for the instructions.

2004 GMC Envoy. My ac is causing my engine to fluctuate in RPM's and will cause engine to die somtimes. If I turn ac off it will idle just fine. Need help.


The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean.

2004 envoy stalls whne ac is turned on


Throttle body needs cleaning, build up of grime prevents butterfly from closing completely. Make sure to disconnect battery for at least 30 minutes while cleaning TB, this will allow PCM to relearn to cleaned TB.
